Compressed air consumption
The compressed air consumption of a blasting machine is only determined by the following factors:
Direct pressure method (one hose):
- Diameter of the blast nozzle
- the blasting pressure.
Suction feed method (two hoses to the blastgun):
- diameter of the air nozzle inside the gun
- the blasting pressure.
Blastpot contents, piping or hose diameter do not influence the consumption.
The following table shows you the compressed air consumption with different diameters and blasting pressures:

Our Spanish distributor MPA uploaded a nice video to their YouTube channel. It shows the restoration of a 1965 Renault Caravelle. It was their customer's first blasting job ever. They used a 5 m3/min compressor together with one of our after coolers and ECO series blastpots. It took them 6 hours to finish the job with only 300 kg of fine abrasive!

-
The new Gritco BC series nozzles have a very wear resistant boron carbide lining so they can be used for all abrasives including aluminium oxide. The nozzles have a long venturi shape with a wide entry. This increases abrasive velocity and creates a wide and even blast pattern. The aluminium jacket has a coarse thread/50 mm to fit standard nozzle holders. The jackets have an extra rubber
